Product List for Bearings, Seals & Crossflon PTFE Sliding Systems
CROSSFLON J BEARINGS
Crossflon J is an all polymeric reinforced PTFE compound that was designed specifically to run against soft mating surfaces such as 316 & 303 Stainless Steel, aluminum, mild steel and other polymer materials. In addition, Crossflon J has excellent static properties and is ideal for small driving forces particularly where start/stops and reverse motion are needed.
Load
Crossflon J bearings are capable of static load pressure of 0.26 psi.
Speed
As with most of the Crossflon range, dry running speeds up to 2m/s are achievable at low pressures.
Friction
Excellent frictional propreties: 0.12 static, 0.13 dynamic, stick/slip is virtually eliminated.
Mating Surface
As stated, Crossflon J has been designed to run successfully against soft counterfaces: Aluminium, non-ferrous metal, Stainless Steel or even plastics.
Temperature
Because of the higher coefficient of thermal expansion, Crossflon J bearings are designed to operate between -30ºC and +95ºC
Surface Finish
Surface finish ideally should be in the region of 0.2 - 0.4µm
Chemical Resistance
Excellent chemical resistance to most acids, bases and solvents
Bearing Failure
Elavated temperature, heavy loads and impact under loading will not cause Crossflon J bearings to shatter, the bearing will merely deform. This eliminates catasrophic failure, which can cause damage to other components.
